Ingredients:
4 cups flour
4 egg yolks
1/3 cup milk
1/2 cup butter
3 leveled tablespoons yeast
1 leveled teaspoon salt
1 lb. ground beef
Vegetable oil for frying (you may also use olive oil)
1 small onion
Parsley
Tomato sauce
Directions:
Warm the milk until lukewarm, then crumble the yeast into it with your fingertips.  Add 1 cup flour and mix all into a smooth dough. Cover and let stand in a warm area to rise.



Next, add the butter, egg yolks, salt and the rest of the flour and stir well. Knead into a tight and elastic dough. If necessary, add water or flour. Cover with a towel and again set in a warm place to rise a second time. Then knead once more to knock down the dough.

Break into small pieces.

During the rising of the dough, cook the ground beef.  Mix it with 2 tablespoons of butter, a finely chopped onion, chopped parsley and a small quantity of tomato.  Cook well, adding 4 or 5 tablespoons of grated cheese just before it is finished.

Take a small piece of dough and roll it flat, on a floured board with a rolling pin. Lay one spoonful of cooked ground meat in the center of the dough. Fold the dough in half to form a half-moon shape and enclose the filling. Shape it a little in the palm of your hand to make a more oval shape.

Smear with egg white. Place on a greased baking tin and set aside in a warm place to rise.

Then deep-fry the turnover in oil until each turns a golden brown. Take them from the oil with a perforated spoon, lay on paper towels to drain and serve them warm.

Here are some variations to this piroski recipe:
1. Instead of frying the turnovers, you can bake them in an oven. In this case, after wrapping the turnovers, put them in a buttered baking pan to rise. Brush the tops with egg white. Then put them in a moderate oven and bake until brown.

2. The meat filling can be made from lean chicken, ham, fish or hard-boiled eggs, chopped and mixed with bechamel sauce or mashed potatoes.

3. Another variation is sweet Russian turnovers. Add 3 tablespoons of sugar together with the salt to the dough. Fill with jelly or marmalade and chopped candied fruit. Sprinkle with powdered sugar and serve. This is a great dessert turnover option!
